    Abstract

    The interdiffusion behavior between cyclic and linear polystyrenes with high molecular weight based on dynamic secondary ion mass spectroscopy (DSIMS) in conjunction with neutron reflectivity (NR) measurements was investigated. Polymers used in this study are monodisperse cyclic and linear PSs (c-hPS, 1-hPS) and those deuterated counterparts (c-dPS, 1-dPS). Time evolution of interfacial thickness with annealing was evaluated by NR and DSIMS. The broadening of the (c-hPS/c-dPS) interface takes place much more rapidly than that of corresponding linear ones. The diffusion of cyclic polystyrene is much faster than that of linear polystyrene. Both thickness of (c-hPS/c-dPS) and (1-hPS/1-dPS) interfaces increase with increasing temperature at 120°C, and that of (c-hPS/c-dPS) bilayer films is much higher than that of (1-hPS/1-dPS) ones at any given temperature.
